In August 2016, a Southwest flight made a safe emergency landing in Pensacola, Fla., after a fan blade separated from the same type of engine, and debris ripped a foot-long hole above the left wing. The 2016 incident prompted the U.S. Federal Aviation Administration (FAA) to propose ultrasonic inspections of similar fan blades and their replacement should they fail the test.
The FAA had "determined the unsafe condition described previously is likely to exist or develop in other products of the same type design," according to its proposal last year.


'Tammie Jo Schults the pilot came back to speak to each of us personally. This is a true American hero,' passenger Diana McBride wrote on Facebook. Schults, right, was one of the first female fighter pilots in the U.S. military and was at the controls when the jet landed. (Facebook)
The European Aviation Safety Agency (EASA) issued an airworthiness directive last month requiring a one-time ultrasonic inspection of each affected fan blade on models of CFM56 engines within nine months of April 2. It said that CFM had sent a service bulletin recommending inspections, leading regulators to make the directive. EASA said the directive was issued after the failure of a fan blade on a CFM56 engine, which led to the uncontained release of debris.

It sure sounds like it isn't limited just to Southwest.
